DISI'NFECT ING APPARATUS.

SPECIFICATION forming pat of Letters Patent No. 523,803, dated Jul 31,1894.

' Application filed January 31,1894. Serial No. 498,546. (NomodeL) useful Improvements in Disinfecting Apparatus, of which the following, taken in con nection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to new and useful improvements in devices for disinfecting apart ments, or to purify or relieve the air in rooms or spaces of odious odors, and the object of the invention is to construct an apparatus capable of automatically allowing a suitable disinfecting liquid to vaporize and combine with the air, that will be more simple and effective than others.

My invention consists in the combination in a disinfecting device of two receptacles placed one above the other, a rib or flange on the upperreceptacle to rest upon the top edge of the lower one, perforations in the side walls of the lower receptacle, absorbent material in the same, and a straight tube extending from the upper receptacle to or near the bottom of the lower receptacle. And my invention consists in certain other combinations of parts, hereinafter described and particularly set forth in the claims.

In the drawings forming a part of this specification, Figure 1- is a side elevation of the apparatus. Fig. 2isa transverse vertical section of Fig. 1. Fig. 3 is a side elevation of the reservoir or upper receptacle and itstube for feeding the disinfectant liquid to the absorbent material on the bottom of the lower receptacle, and Fig. 4 is a view of a modified form taken on line, as, of Fig. 3.

Referring specifically to the drawings, A is the lower receptacle which has preferably a cylindrical shape and is formed of thin metal. Near the top of this receptacle and in the sides thereof are several rows of perforations B, one above the other to allow the air to circulate therethrough. In the bottom of the same receptacle is a strip of absorbent material O as lamp wicking, suitably folded at its ends, as shown in Fig. 2 of the drawings, for r the purpose of absorbing gradually the disinfecting liquid and exposing it to the air, The

straight tube, E, communicates with and ex 7 tends from the bottom of the upper recepta cle D to the wicking, C, in the bottom of the receptacle A. The lower end of this tube isnotched as shown and is preferably provided with a plug of asbestus or other fibrous material, 0, so that the liquid disinfectant will pass from the reservoir or receptacle, D, through the tube tothe wicking, slowly, yet effectively. The upper receptacle is provided with athreaded cap b, which is removed when the disinfecting liquid is exhausted for the purpose of replenishing the supply. 1

Instead of placing a plug, 0, of fibrous material in the lower end of the tnbe,E, and the folded wicking in the lower receptacle, I may cast or mold a block, F, of plaster of paris or other similar absorbent material around and below the end of the tube, E, as shown in dotted lines in Fig. 3 and in the plan view in Fig. 4 of thedrawings. In this case a large surface may be exposed to the air by molding the block with corrugations as indicated in the last figure, and the tube E may be perforated as shown in Fig. 3.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a disinfecting apparatus, the combination, of a perforated receptacle containing absorbent material, a fluid-holding receptacle, having its lower portion fitted within the upper open end of the perforated receptacle and provided with a tube extending to near the bottom of said perforated receptacle and provided with notches at its lower end, and an absorbent material at the end-of said tube, substantially as specified.

2. In a disinfecting apparatus, the combination, with a receptacle having perforated sides, of a liquid-holding receptacle having its lower end fitted within the upper open end of said perforated receptacle and provided forations, and a block of absorbent material, surrounding said lower end of the tube and provided with corrugated sides, substantially as specified. p

In testimony whereof I have hereunto signed my name.

I WARREN M. BRINKERHOFF. [It 8.]
